I acted upon by frictional means to hold it in Also the vapour 'rijsing from the heated adjusted position.

The wall L is cut away adjacent the aperture I of the chamber H.

The vaporizing liquid is poured into the chamber H through the aperture K and any overflow will pass through the cut away portion of the bowl L into the bowl D. A tube M of any desired diameter is supported adjacent one of its ends by the upstanding wall L about the aperture K in such manner that its outer end may be swung into or out of the bowl D. The means for so supporting the tube M comprises a bracket member N which has one end bent into an arm N parallel with the tube M. Said arm N is secured against wall L by a bolt P which is encircled by a spring washer Q. A nut R threaded on to the stem of the bolt P holds the spring washer Q under compression to cause frictional contact between the arm N and the wall L so that the tube can be held in any position. The tube M carries a wick S which extends into the wall L and the annular chamber H so that by capillary action the vaporizing liquid is carried from the annular chamber H to the bowl D in a manner well known.

The free end of the tube M is preferably angled and projects over the bowl D and such tube M can be positioned and by the frictional contact of the arm N with the wall L be held in any placed position. WVhen the tube M is positioned as at Figure 1 the supply of vaporizing liquid is cut oil and any liquid in the tube and the wick contained therein will flow back into the annular chamber H, but when the angled end is positioned as in Figure 2, the wick being always sufiiciently impregnated will cause the vaporizing liquid by syphonic action, to flow and drip into the bowl D to be vaporized by the heat from the heating medium in the body B and by positioning the tube M at various angles with the angled end below the horizontal, the supply of vaporizing liquid is varied.

The tube M is limited in its upward move ment by the end of the arm N abutting a stop T projecting from the wall L and in a down ward direction by the arm N engaging the wall L.

What I do claim as my invention and desire to obtain by Letters Patent is 1. In a vaporizer, a vaporizing bowl, a chamber to contain liquid to be vaporized, a wick to supply the liquid from the chamber to said bowl, and means operable to adjust the dischar e end of the wick to control the supply of liquid to said bowl.

2. In a vaporizer, a vaporizing bowl, a chamber to contain liquid to be vaporized, a wickto supply the liquid from the chamber to said bowl, means over which said wick passes adjustable so as to adjust the discharge and of the wick to control the supply of liquid and to drain into the bowl when the supply of liquid is cut off by such adjustment.

3. In a vaporizer, a vaporizing bowl, a chamber to contain the liquid to be vaporized, a wick to supply the liquid from the chamber to said bowl, a tube through which the wick passes, means mounting the tube for vertical adjustment at its discharge end and in relation to the chamber for drainage when the supply is cut ofi through adjustment.

4. In a vaporizer according to claim 3, friction means to secure the first mentioned means in its adjusted positions.

5. In a vaporizer according to claim 3, a duct communicating with said chamber, said tube being pivoted to said chamber.

6. In a vaporizer, a. vaporizing bowl, a chamber to contain liquid to be vaporized, a duct extending from the chamber, a wick extending through the duct to su ply the liquid from the chamber to said bowl, a tube through which the wick passes disposed over the bowl and pivoted to the duct, and a friction means whereby the tube will be held in diflerent adjusted positions.

7 In a vaporizer, a supporting body provided with a bowl, a chamber member thereon to contain liquid to be vaporized, said member having a flange coinciding with the wall of the bowl, the top wall of the chamber member having an opening and a duct about the same, a tube adjustably mounted on said duct on a horizontal axis and over said bowl, and a wick passing through the duct and lt)ube to supply fluid from the chamber to the owl.

8. In a vaporizer according to claim 7, means to support a heating medium below the bowl, and means to secure the tube in different positions of adjustment.

In testimony whereof I have hereunto set my hand. i

ALBERT FRANK PORTER.
